I had a T-Bolt 'failure' when my -12V supply died. I am aware of another event on the list when the solder connection at the -12V connector to the t-Bolt failed.
Make sure the -12V is reaching the PCB for the T-Bolt. Hope this helps.

Hi Dave, There was one other report of something similar over the past ten years. I did not look into it. Since your TBolt was part of the group buy, I'll send you a new one. Contact me off-list. But can you double check the -12 V power supply voltage for me? Anything between -7 and -15 is probably ok. But if it fails it will affect the serial port. Also, if you have time, open the box and use a 'scope on both the input (TTL) and output (RS232) of the serial transceiver.
